Thanks! I don't know, if anyone has got deep enough into it, to consider this, but I'm pondering on a way to make the random procedure repeatable. Now, the machine picks some random numbers as it plays, so it's quite impossible to re-play an evolving/randomized sequence, unless you record the out-coming audio. I have this idea to generate a group of random numbers beforehand and then use them while playing, this way the random sequence will be perfectly re-playable. I'm trying to implement such feature now. Any thoughts on the idea?
